The paper deals with the investigation of some phenomena which are essential for dynamic interaction of a wheelset or bogie with the railways track. The track is modeled as discrete-continuous system composed of rails, fastening systems... more
Planting bushes and trees in and around sound generating sources is an effective solution for noise pollution. Urban Planning, Public Education and Awareness. Regular servicing and tuning of automobiles/ machinery can effectively reduce... more
The purpose of this paper Project is to create a workplace toxicant intervention for Metropolitan Hospital of Denver, a large top-rated surgical facility located in Denver, Colorado. The project lays out the steps necessary to make... more
Background: Extrovert and introvert subjects' attention levels are affected by exposure to noise. The aim of this study was to investigate the effects of stress (noise) on selective attention of university students. Methods: Exposure to... more
El soroll ambiental s'ha convertit en una de les majors fonts de malestar en tots els països desenvolupats (García, 1988) (Calvo-Manzano et al., 1991)*. En una població com Banyeres de Mariola es produeix un cúmul de factors que... more
The requirements set by the most important Air Traffic Management (ATM) research initiatives (SESAR and NextGen) and environmentally sustainable aviation research initiatives (Clean Sky, and Environmentally Responsible Aviation), aim at... more
As demand for computer software continually increases, software scope and complexity become higher than ever. The software industry is in real need of accurate estimates of the project under development. Software development effort... more
Talk: Impulse noise and vibrations in buildings are common from weight drops in gyms. There are a growing emphasis and literature on the matter, often supported by the floor or mat-industry. We will show measurements of impacts from free... more
The limits of the procedure for the measurement of the sound insulation of building façades represent the main subject of this paper. To calculate the façade insulation, standard ISO 140-5 requires that the difference between outdoor and... more
Vibration Fatigue Analysis in the finite Element Environment
It addresses different situations and calculations of sound pressure intensity (noise). This material belongs to the Civil Eng. Of Labor Safety Josevan Ursine Fudoli.
This research presents a thorough evaluation of the reverberation room at Acoustics Laboratory in National Institute of Standards (NIS) according to the related international standards. The evaluation aims at examining the room... more
Noise is consistently presents in digital images during image acquisition, coding, transmission, and processing steps. The main purpose of de-noising the image is to restore the detail of original image as much as possible. Depending on... more
Experience in the gas production, petrochemical, and other industries has demonstrated that acoustic energy in high capacity, gas pressure reducing systems can cause severe piping vibrations, and in extreme cases have led to piping... more
The Internet of Things (IoT) concept facilitates our life in many areas. One of the facilities provided in this area is undoubtedly condition monitoring. Unlike regular maintenance, IoT systems that perform continuous control operations... more
This application report shows how to implement a single channel active adaptive noise canceller with the low cost Texas Instruments (TIä) TMS320C50 (‘C50) digital signal processor (DSP) starter kit (DSK). Once the needed equipment is... more
This paper contains the Finite Element Analysis (FEA) of a cantilever beam. I have used the FEM software COMSOL Multiphysics V5.2. I have simulated the effect of eigenfrequencies on a cantilever beam. The properties are of structural... more
Computer Aided Engineering (CAE) has been an important tool in the process of automotive product development. Chassis of the automobile are subjected to excitations from the road conditions and due to engine operations during their life... more
Images of Molecules are broadly used to foresee atom properties in educating and synthetic exploration. A prepared physicist can undoubtedly infer particle properties by dissecting its construction and assess its useful gatherings. To... more
Objectives: The project are to identify, analyse and assess hazard that available at Sipro Plastic Industries Sdn Bhd. To improve and to propose a better workplace condition by implementing and proposing a possible control measure and... more
The EU Directive 49 urges countries to prepare the strategic noise maps and the action plans for the agglomerations along major transportation routes and major industrial premises. Environmental engineers, town planners and architects are... more
Kenyamanan sebuah lingkungan atau sebuah ruang sangat salah satunya bergantung pada tingkat kebisingan dari ruang atau lingkungan tersebut. Untuk mengurangi tingkat kebisingat yang diterima sebuah lingkungan yang dekat dengan sumber... more
Prior experience with attempts to isolate the vibrations of dry-type transformer cores within an electrical unit substation required isolation of the full substation casing to achieve sufficient noise reduction to the occupied space... more
Highlights: (1) Tanker with twin podded propulsion was simulated in waves using CFD to obtain wake variation. (2) Effect of wake change, ship motions, RPM variation and speed loss has been studied. (3) Significant increase in... more
